d) ASTM B380 (Corrodkote): this test shall be applicable to SC-2 devices and shall have a duration of
4 h.
Note: If more than one test method is specified, the manufacturer may specify which method is to be used. SC-1
and SC-2 are defined in Clause 3.1.
5.2.2.2.2
An SC-1 specimen that passes the SC-2 test shall be considered to have met the requirements of
Clause 5.2.2.2.1.
5.2.3 Adhesion
5.2.3.1 Performance requirements
The coating and the separate layers of multi-layer coatings shall be sufficiently adherent to each other
and to the base material to comply with one of the adhesion tests specified in Clause 5.2.3.2, 5.2.3.3, or
5.2.3.4, as applicable.
5.2.3.2 Electrodeposited and PVD coatings on metals
Specimens shall be tested in accordance and comply with one of the following adhesion tests specified
in ASTM B571:
a) Paragraph
4: burnish test;
b) Paragraph
7: file test;
c) Paragraph
8: grind-saw test; or
d) Paragraph
9: heat-quench test.
5.2.3.3 Electrodeposited and PVD coatings on plastics
5.2.3.3.1 Performance requirements
Fittings or component parts of fittings that have electrodeposited coatings on plastic bases, including
those with additional organic coatings, shall comply with the following requirements when tested in
accordance with Clause 5.2.3.3.2:
a) No
surface defects shall be present on significant surfaces.
b) Non-significant
surfaces, gates, and parting lines may have minor cracks not longer than 6
mm
(0.25
in), provided that there is no loss of adhesion between the base material and the coating.
c) Blis
ters not exceeding 6 mm
2
(0.01 in
2
) in area shall be acceptable within 6 mm (0.25 in) of an
injection point. If an injection point is within 6 mm (0.25 in) of a significant surface, Item a) shall
apply.
d) Warpage shall be considered acceptable only where it does not affect the performance of the
fitting or component.
The adhesion of organic coatings shall be evaluated following the procedure specified in Clause 5.2.3.4
and shall not be evaluated during the test specified in Clause 5.2.3.3.2.
5.2.3.3.2 Thermal cycling procedure
Before the thermal cycling test begins, the fittings or component parts of fittings shall be examined and
surface imperfections (e.g., small mould imperfections) shall be noted. These surface imperfections shall
not be considered failures after the thermal cycling test unless they develop into surface defects.
